Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509226, here are decompositions:

5 + 31509221 = 31509226
53 + 31509173 = 31509226
149 + 31509077 = 31509226
173 + 31509053 = 31509226
197 + 31509029 = 31509226
227 + 31508999 = 31509226
383 + 31508843 = 31509226
479 + 31508747 = 31509226

Showing the first eight; more decompositions exist.
